Understanding BNWAS and Its Significance
A Bridge Navigational Watch Alarm System (BNWAS) is a mandatory safety device on board ships to identify incapacitation or inactivity of bridge officers. The system would ensure that if the watch officer does not respond to warning alarms within a set duration, alarms increase to alert other crew members, minimizing chances of navigational malfunctions or ship collisions.
Why BNWAS Is Mandatory
Global maritime law, such as SOLAS Chapter V, requires BNWAS installations on all vessels with a gross tonnage of more than 150. Adherence to IMO MSC.128(75) guarantees that vessels are fitted with dependable alerting systems, thus promoting crew safety and operational effectiveness.
Introducing the Seab Marine DMA-105 BNWAS Monitor Display
Seab Marine’s DMA-105 BNWAS Monitor Display is engineered to the highest level of navigational safety. It combines state-of-the-art technology with a user-friendly interface, offering real-time monitoring and alarm escalation to avoid bridge inattention.

High-Resolution Display – The display has a bright, high-contrast screen for clear visibility, even under low-light conditions.
User-Friendly Interface – Easy controls allow rapid configuration and response in emergency situations.
Alarm Escalation System – Cumulative alarm activation involves voice, visual, and remote notifications to ensure response prior to critical events.
Tamper-Proof Design – Locked functionality discourages illegal deactivation or system bypassing.
Multiple Activation Modes – Manually or automatically, the system may be activated on activity monitoring.
Automatic Watch Reset – Smart sensors monitor officer activity and adjust the alarm countdown accordingly.

How Does the DMA-105 Enhance Maritime Safety?
The Seab Marine DMA-105 is designed to prevent the risk of unmanned bridges by mandating active watchkeeping. Here’s how it enhances safety at sea:
Avoids Fatigue-Related Mistakes – Ongoing monitoring guarantees that a vigilant and alert officer is always available.
Eliminates Human Error in Navigation – The system prevents accidents brought about by brief attention lapses.
Complies with Maritime Laws – Vessels that are equipped with DMA-105 are inherently compliant with SOLAS and IMO regulations.
Rapid Emergency Response – The innovative alarm system ramps up from subtle warning to full-ship alerts in case of no response.
Improves Crew Coordination – In the case of non-response, the system gives warning to backup personnel to avoid severe navigation failure.
